Multiple arterial and venous thromboembolism in a male patient with hereditary protein C deficiency: A case report.

Medicine (Baltimore) 2021 Apr;100(15):e25575

Department of Vascular Surgery, The Second Xiangya Hospital of Central South University.

Rationale: Hereditary protein C deficiency has a high prevalence in Asian populations, being the important risk factor associated with thrombophilia. Traditionally, conservative medication is the first choice for patients with hereditary protein C deficiency. However, there are few reports on whether aggressive surgical treatment can be performed when patients continue to develop life-threatening ischemic symptoms after adequate anticoagulant and thrombolytic therapy.

[Alcohol septal ablation for hypertrophic obstructive cardiomyopathy: the emerging role of the Cardiomyopathy Team].

G Ital Cardiol (Rome) 2021 Mar;22(3):25-31

U.O. Cardiologia e Angiologia, Dipartimento di Scienze Cardiovascolari, Sapienza Università di Roma, Roma.

Alcohol septal ablation is a minimally invasive, safe, and effective procedure for the treatment of left ventricular outflow tract (LVOT) obstruction in patients with hypertrophic obstructive cardiomyopathy (HOCM) who remain symptomatic despite maximal medical therapy. Originally performed by Ulrich Sigwart in 1994, the procedure causes a iatrogenic infarction - through the injection of absolute alcohol - of the basal portion of the interventricular septum and aims at reducing LVOT obstruction in order to improve patient's hemodynamics and symptoms. Numerous studies have demonstrated the effectiveness and safety of the procedure, making it a valid alternative to surgical myectomy. Read More

Relationship between small dense low density lipoprotein and cardiovascular events in patients with acute coronary syndrome undergoing percutaneous coronary intervention.

BMC Cardiovasc Disord 2021 Apr 12;21(1):169. Epub 2021 Apr 12.

Department of Outpatient, Beijing Friendship Hospital, Capital Medical University, Beijing, 100050, China.

Background: Residual risk remained significant despite effective low density lipoprotein cholesterol (LDL-C) lowering treatment. Small dense low density lipoprotein cholesterol (sdLDL-C) as part of LDL-C has been found to be predictor of coronary heart disease (CHD) and cardiovascular (CV) events in patients with stable CHD independently of LDL-C. However, to date, few studies have explored the role of sdLDL-C in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI). Read More

Cardiac Fibroblasts and Myocardial Regeneration.

Front Bioeng Biotechnol 2021 25;9:599928. Epub 2021 Mar 25.

Department of Biomedical Engineering, School of Medicine and School of Engineering, University of Alabama at Birmingham, Birmingham, AL, United States.

The billions of cardiomyocytes lost to acute myocardial infarction (MI) cannot be replaced by the limited regenerative capacity of adult mammalian hearts, and despite decades of research, there are still no clinically effective therapies for remuscularizing and restoring damaged myocardial tissue. Although the majority of the cardiac mass is composed of cardiomyocytes, cardiac fibroblasts (CFs) are one type of most numerous cells in the heart and the primary drivers of fibrosis, which prevents ventricular rupture immediately after MI but the fibrotic scar expansion and LV dilatation can eventually lead to heart failure. However, embryonic CFs produce cytokines that can activate proliferation in cultured cardiomyocytes, and the structural proteins produced by CFs may regulate cardiomyocyte cell-cycle activity by modulating the stiffness of the extracellular matrix (ECM).

The innate immune response in myocarditis.

Int J Biochem Cell Biol 2021 Apr 5;134:105973. Epub 2021 Apr 5.

School of Cardiovascular Medicine and Sciences, King's College London British Heart Foundation Centre of Excellence, James Black Centre, 125 Coldharbour Lane, London, SE5 9NU, UK. Electronic address:

Acute myocarditis is an inflammatory condition of the heart characterised by cellular injury and the influx of leucocytes, including neutrophils, monocytes, macrophages and lymphocytes. While this response is vital for tissue repair, excessive scar deposition and maladaptive ventricular remodelling can result in a legacy of heart failure. It is increasingly recognised as a clinical phenomenon due, in part, to increased availability of cardiac magnetic resonance imaging in patients presenting with chest pain in the absence of significant coronary artery disease.

Early Thrombectomy Protects the Internal Capsule in Patients With Proximal Middle Cerebral Artery Occlusion.

Stroke 2021 Apr 8:STROKEAHA120031977. Epub 2021 Apr 8.

Department of Diagnostic and Interventional Neuroradiology, Klinikum rechts der Isar, School of Medicine, Technical University Munich, Germany (J.K., M.K., M.B., C.M., S.M., C.Z., T.B.-B., J.F.K.).

Background And Purpose: Proximal middle cerebral artery (MCA) occlusions impede blood flow to the noncollateralized lenticulostriate artery territory. Previous work has shown that this almost inevitably leads to infarction of the dependent gray matter territories in the striate even if perfusion is restored by mechanical thrombectomy. Purpose of this analysis was to evaluate potential sparing of neighboring fiber tracts, ie, the internal capsule. Read More

Cureus 2021 Feb 27;13(2):e13599. Epub 2021 Feb 27.

Department of Emergency and Critical Care Medicine, Kitasato University School of Medicine, Sagamihara, JPN.

The incidence of thrombotic complications is extremely high among severe coronavirus disease 2019 (COVID-19) patients in the intensive care unit. Various factors such as a cytokine storm due to an excessive immune response to inflammation, hypoxemia, and disseminated intravascular coagulation are considered predisposing factors for thrombotic complications. A 55-year-old Japanese man intubated eight days previously was referred to our hospital because of a severe COVID-19 pneumonia diagnosis after his pharyngeal swab tested positive for severe acute respiratory syndrome coronavirus 2 using reverse transcription-polymerase chain reaction.

Axial flow ventricular assist devices in cardiogenic shock complicating acute myocardial infarction.

Heart 2021 Apr 2. Epub 2021 Apr 2.

Cardiology, Saint James's Hospital, Dublin, Ireland.

Cardiogenic shock (CS) remains the leading cause of death in patients hospitalised with acute myocardial infarction with mortality as high as 40%-50% prior to hospital discharge. The failure of inotropic therapy to maintain adequate perfusion and to prevent irreversible end-organ failure has led to attempts to improve outcomes by mechanical circulatory support (MCS) devices. Axial flow ventricular assist devices, namely Impella, are an attractive therapeutic option due to their positive haemodynamic benefits and ease of use. Read More

The Role of Circulating Biomarkers in Peripheral Arterial Disease.

Int J Mol Sci 2021 Mar 30;22(7). Epub 2021 Mar 30.

Laboratory of Atherothrombosis, Program of Cardiovascular Diseases, Cima Universidad de Navarra, 31008 Pamplona, Spain.

Peripheral arterial disease (PAD) of the lower extremities is a chronic illness predominantly of atherosclerotic aetiology, associated to traditional cardiovascular (CV) risk factors. It is one of the most prevalent CV conditions worldwide in subjects >65 years, estimated to increase greatly with the aging of the population, becoming a severe socioeconomic problem in the future. The narrowing and thrombotic occlusion of the lower limb arteries impairs the walking function as the disease progresses, increasing the risk of CV events (myocardial infarction and stroke), amputation and death.
